Given numbers are 178, 688, 309, 122

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(178, 688) = 61232

GCD(178, 688) = ( 178 x 688 ) / 61232

= 178 / 688

= 178

Step2:

LCM(2, 309) = 618

GCD(2, 309) = ( 2 x 309 ) / 618

= 2 / 309

= 2

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 178, 688, 309, 122 is 1
